Kuinka granuliitti syntyy / Making a granulite

Tässä kuvassa näkyy syntymässä oleva granuliitti: biotiitti- ja sillimaniittipitoinen gneissi sulaa osittain ja tuloksena on granuliittia eli granaattia ja kordieriittia sisältävä kivi, jota juonittaa sulamisessa syntynyt graniittinen aines. Graniittinen aines on kuvassa valkoista, granaatti ruskehtavan punaista ja kordieriitti sinistä kun taas biotiittipitoinen lähtömateriaali on tumman harmaata.

In this image you can see how granulite is formed by partial melting of a biotite-sillimanite gneiss (grey). As a result of the reaction garnet (red), cordierite (blue) and migmatizing granite (white, melt during the reaction, but crystallized during cooling) are formed.
